Using linear operators to approximate signals of Lip(; p); (p ≥ 1)-class

Abstract. In this paper, we investigate trigonometric polynomials associated with f ∈ Lip(; p); (0 ≤ ≤ 1; p ≥ 1) to approximate f in Lp norm to the degree of O(n−)(0 < ≤ 1) for a more general class of lower triangular regular matrices with non-negative entries and row sums tn. 1
